Chapter 9 OpenSIGLE - Crossroads for Libraries, Research and Educational Institutions in the Field of Grey Literature Dominic J. Farace and Jerry Frantzen, Grey1et International, 1etherlands Christiane Stock and 1athalie Henrot, I1IST-C1RS, France Joachim Schöpfel, University of Lille 3, France 9.1 Introduction This chapter is based on a paper1 presented at the Tenth International Conference on Grey Literature (GL10) in which GreyNet’s collections of conference preprints were made accessible via the OpenSIGLE Repository. OpenSIGLE offers a unique distribution channel for European grey literature with roots dating back a quarter century. In the first part of the chapter, the experience of INIST as service provider and GreyNet as data provider will be discussed including recent devel- opments. Later in the chapter, the draft of a project proposal called for in the final ses- sion of that conference will be elaborated. The proposal seeks to explore the ca- pacity required for the OpenSIGLE Repository to develop in multilateral and international cooperation in support of European research infrastructures commit- ted to the open access of grey literature collections and resources. Emphasis is placed on the involvement of libraries, research centers, and institutions of higher education, as well as, requirements for a grey literature network service to sustain further development, exploitation, and promotion of the OpenSIGLE Repository. 9.2 From SIGLE to OpenSIGLE: A Progress Report SIGLE (System for Information on Grey Literature in Europe) was a unique mul- tidisciplinary database dedicated to grey literature. Up to 15 European partners participated in SIGLE, mostly national libraries or libraries aligned to well-known 1 Farace, D.J., J. Frantzen, C. Stock, N. Henrot, and J.

Their principal goals were the centralized collection of scien- tific and technical reports, theses and other grey material and to facilitate access to these documents through an engagement for document delivery or loan. Created in 1980 and produced from 1984 onwards by EAGLE (European Association for Grey Literature Exploitation), the database was last available through STN Inter- national and on CD-ROM via Silverplatter/Ovid until it became dormant in 2005. INIST then decided to make the data publicly available on an open access plat- form. Details of the migration from SIGLE to OpenSIGLE have been presented at the GL8 Conference2 held in December 2006 (Schöpfel 2007). And in December 2007, the OpenSIGLE website3 went live. This chapter further discusses three related issues dealing with OpenSIGLE: (1) usage statistics covering two years of access to the repository, (2) a bilateral cooperative agreement with GreyNet, the Grey Literature Net- work Service, and (3) a project proposal exploring the capacity required for the OpenSIGLE Repository to develop in multilateral and international cooperation. 9.2.1 OpenSIGLE Traffic Report Usage information for a database is at all times interesting for the producer of the information. In this case an additional incentive was the fact that OpenSIGLE records, which migrated from the SIGLE database, had not been updated since 2005. Would then the move to an open access environment be at all “useful” for the grey literature community? The usage analysis is based on data obtained through phpMyVisites, an open source software for website statistics that works with a javascript image call. Only completely uploaded pages are counted and robots are excluded. The following data provide only a part of the information that can be obtained through phpMy- Visites. Other statistics based on server logs might however provide even higher figures. The first figure shows that the number of visits as well as the number of page views has increased steadily since the opening of the website in 2007. A first peak was reached in July 2008 following a press campaign in the middle of the French holidays. The result is both surprising and rewarding since visits usually decrease during summer months. The usage of OpenSIGLE continues to increase. In terms of page views and number of visits in which the average duration is 90 seconds, the increase is well over four times the amount in March 2010 compared to March 2009.

OpenSIGLE is in third place among users from this continent preceded by the English version of INIST’s institutional website4 and IndicaSciences5 - an INIST product dedicated to research evaluation and indicators. INIST websites geared to a French speaking audience receive an average of 7% of the visits from North America. The analysis of web links as well as feedback through incoming messages re- veal that OpenSIGLE is often used in the biomedical and public health sectors. However, at present, statistics do not allow us to go into further detail regarding scientific domains. During the course of 2008, several requests were received from former users of the STN or Ovid versions of the SIGLE database dealing with complex search strategies. Such questions required another look into the limits of the Jakarta Lu- cene search engine implemented within DSpace, especially with regard to the length of the search query. It was discovered that Lucene allows for more possi- bilities than mentioned in the help provided by DSpace. Besides inquiries involv- ing search strategies, users were also interested in the download and export fea- tures of OpenSIGLE. One critical view of OpenSIGLE found on a blog6, mentions the absence of links to the full text of documents. Of course this is understandable given the fact that it was one of the very reasons why the SIGLE database was discontinued. 4 English version of INIST’s institutional website, http://international.inist.fr 5 INIST product dedicated to research evaluation and indicators, http://indicasciences.inist.fr 6 Critical view of OpenSIGLE found on a blog, http://healthinformaticist.wordpress.com/ 2008/08/28/does-opensigle-exist-for-its-own-sake/ OpenSIGLE - Crossroads for Libraries, Research and Educational Institutions 145 9.2.4 Promotional Activities Before the official announcement of the launch of OpenSIGLE, the project was presented at a DSpace meeting focused on the exchange of experiences among its users (Grésillaud and Stock, October 2007) 7. Shortly afterwards, and as a result of that meeting, visitors from Spain and Italy were observed on the OpenSIGLE website. In December 2007, INIST also focused attention on OpenSIGLE during the GL9 Information Walk-Thru at the Ninth International Conference on Grey Literature in Antwerp, Belgium8. In May 2008, a short presentation for the French public was given at I-expo (IT conference and exhibit) in Paris. And in July, INIST sent a press release to national and international lists and agencies i.e. Information World Review and Research Information. This no doubt resulted in the above mentioned peak of visits in the middle of summer. A brief message about OpenSIGLE was placed simultaneously on the French and international homepages of INIST. Since “news items” are normally less frequent during summer months, the message remained for a longer period of time on these WebPages. Today OpenSIGLE is indexed by Google and Google Scholar and included in the bookmarks of national libraries and research institutes. Following the creation of the WorldWideScience Alliance and website9 in June 2008, INIST (a partner in this Alliance) proposed to integrate OpenSIGLE into the WorldWideScience por- tal.
